Upcoming changes to Cinderella
We are currently preparing a new version of Cinderella that is mainly a stable release of the current beta version. It does include some cleanups as well, for example a better support for exporting to CindyJS, our …

The Interactive Geometry Software
Download Cinderella Documentation
Free for Windows, macOS and Linux
Experience Geometry on your desktop and on the web
Easily create startling geometric constructions! Starting from simple triangle relations, continuing with trigonometric theorems up to fractals and transformation groups Cinderella lets you create and manipulate visualizations in an intuitive, yet powerful way. Using Java® technologies, constructions are seamlessly exported to the WWW. And even better: you can get this for free!
Use simulations for virtual laboratories
Freely experiment with masses, springs, charges and fields! Liberated from the constraints of reality, scenarios ranging from atom physics, classical mechanic to planetary orbits may be examined. Effortlessly sketch experiments using the mouse and bring them to life with a simple click.
Expand to your needs
With the easy-to-learn functional programming language CindyScript you can extend Cinderella’s behavior to your needs. You can plot functions, move objects automatically, draw arbitrary figures - there is no limit but your imagination.
University-Level mathematics with an intuitive interface
No matter whether you are doing K-12 mathematics or you are into Projective or even Hyperbolic Geometry - Cinderella supports it natively. Internally, Cinderella uses a state-of-the-art mathematical model that combines all these into one. Paired with the continuity features based on analytic functions, you can be sure to learn mathematics, not software.
Teach and share
Cinderella is available for free. This makes it easy to provide all students and teachers with a legal copy of Cinderella that they may use in school and at home. And it runs on Windows, Mac OS X, Linux, and many other Unix variants.
Cinderella is a partner of Intergeo.
